It operates in deep collection pits where effluents carrying substantial suspended solids must be handled under complete submersion. The unit is optimized for liquids from 0 to 40°C requiring continuous-duty service in high-head networks.\u003c\/p\u003e\u003cp\u003eHydraulic performance reaches a maximum total head of 41.5 m and a maximum flow rate of 15000 L\/Min. This 75 kW model draws a rated current of 144 Amps on a 415V three-phase supply at 50Hz. Motor activation is managed by an integrated Star-Delta starting method to control the electrical behavior during activation.\u003c\/p\u003e\u003cp\u003eThe unit utilizes a 4-pole dry-type induction motor at a synchronous speed of 1500 min?¹. A water jacket is equipped around the motor frame where a portion of the pumped liquid cools the motor during continuous operation. A shrouded two-channel impeller for solid-handling design is incorporated, enabling a 90 mm solids passage.\u003c\/p\u003e\u003cp\u003eStructural hardware consists of a Gray Cast Iron JIS FC250 pump body and 420 stainless steel shafting. Standard model is free-standing with an integrated base stand. A guide rail fitting version is available under model code TO300BZ475H, allowing easy maintenance and inspection without entering the collection pit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWater jacket equipped around the motor frame where a portion of the pumped liquid flows into the jacket to cool the motor.\u003c\/li\u003e\n\u003cli\u003eShrouded two-channel impeller for solid-handling design, dynamically balanced.\u003c\/li\u003e\n\u003cli\u003e90 mm solids passage for moving debris through the pump casing.\u003c\/li\u003e\n\u003cli\u003eDouble-face mechanical seal located in oil chamber where both upper and lower seal faces run in a clean environment.\u003c\/li\u003e\n\u003cli\u003eTsurumi Oil Lifter forcibly supplies lubricating oil to the mechanical seal and continues to supply the oil to the upper seal faces even if lubricant falls below the rated volume.\u003c\/li\u003e\n\u003cli\u003eUpper permanently lubricated deep-groove double-shielded C3 ball bearing ensures mechanical stability for the motor shaft.\u003c\/li\u003e\n\u003cli\u003eLower duplex angular contact ball bearing mounted back-to-back for mechanical stability during processing.\u003c\/li\u003e\n\u003cli\u003eAnti-wicking cable entry block prevents internal motor components from moisture ingress via damaged power leads.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50946659254519,"sku":"300BZ475H","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-300bz475h-cast-iron-water-jacket-submersible-sewage-pump-high-flow-two-channel.png?v=1784259442","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-300bz475h-cast-iron-water-jacket-submersible-sewage-pump-high-flow-two-channel","provider":"Foundation Pumps","version":"1.0","type":"link"}
